nAnrA'ron. AND FLYWHEEL.

Application filed April 11,

This invention relates to motors and par ticularly to a novel means for mounting a radiator on the engine block of an internal combustion motor, the mounting being so disposed that the air impeller for passing air through the radiator be conveniently attached to the crank shaft. The air impeller is usually a part of the flywheel and the radiator is substantially circular within the perimeter of the fly-wheel. The radiator is fast to the engine block and the invention resides more particularly in the means for pro viding a practical assembly. V

The novel construction of the invention will be apparent by reference to the following description in connection with the accompanying drawings, in which Fig. 1 is a sectional view through a radiator, an air impeller, and fly wheel, and through part of the engine block, the crank shaft being shown in elevation.

Fig. 2 is an elevational view of the radiator.

Fig. 3 is a detailed perspective view of the mounting member and cap, and

Fig. 4 is a. detailed perspectiveview of the cap. 7

Referring now to the drawings by numerals of reference 1 designates the engine block which may be of any preferred construction and which is provided with a crank shaft bearing 2 to receive one end of a crank shaft 3. The crank shaft has a projecting portion or spindle 4.

Fastened to the engine block is a radiator mounting member consisting of a substantially cone-shaped shell 5 having a peripheral flange 6 secured to the engine block by fastening devices such as screws 7. The coneshaped member 5 carries a radiator supportin cap 8 which is riveted to the cone-shaped member by the rivets 9.

The cap 8 is formed with a ring 10 having a plurality of lugs 11 internally threaded to receive screws 12 which pass through the octagonal shaped portion 13 of the ring 14 which supports the radiator 15. The radiator has two ports 16 and 17, one for the inlet and the other for the outlet. The radiator may be of approved construction and surrounding the radiator is the rim or flange 18 of a flywheel 19 which constitutes the air impeller. The rim 18 is provided with blades 20 and 1924. Serial N0. 705,757.

the hub of the impeller or fly-wheel is carried on the spindle 4:, it being secured against displacement by the nut 21.

The spindle 4 has a collar or flange 22 between which and the inturned flange 28 is a packing 24 to prevent vapors from the crank case from escaping to atmosphere.

In assembling the radiator and fly wheel the mounting member 5 may be first attached to the engine block, then the cap may be riveted by means of rivets 9, then the radiator may be fastened by means of screws 12 which enter the lugs 11. The air impeller and fly wheel may be attached to the spindle and fastened by the nut 21 and locked in any appropriate manner. The parts may be re moved conveniently by taking off the nut, removing the fly wheel and taking out the screws 12 so that the radiator may be removed. It will therefore be seen that the assembly is inexpensive to construct and easy to apply and remove.

l/Vhat I claim and desire to secure by Letters-Patent is:

1. A mounting for the radiator of an engine having a crank shaft and a fan having a radiator-enclosing rim and an inwardly extending hub, comprising a cone-like cap supported by the engine block and provided with an external flange on its outer end, and an inwardly extending flange on the radiator for engagement with said cap flange for supporting the radiator and spacing the radiator from the shaft whereby the fan hub may be mounted on the shaft interiorly of the radiator.

2. A mounting for the radiator of an in ternal combustion engine comprising a oylindrical radiator-supporting ring having flange portions ext-ending inwardly in the plane of the inner vertical face of the radiator, a conical shell for attachment to the en.- gine block having a reduced end for receiving the crank shaft spindle and attaching members extending radially from said reduced end adjacent the rim thereof for engagement with said radial portions, the said radial portions spacing the ring and radiator from the spindle.

In testimony whereof I affix my signature.
